The Future of Carbon fiber-reinforced polymer (CFRP)

High-performance polymers provide
light, stable materials that also resist high temperatures, and find more and
more applications from leisure goods to aerospace.

The Dreamliner from Boeing marked
the launch of a new generation of airliners. Around 50% of the aluminum
formerly used in aircraft construction has been replaced by Carbon Fibre
Reinforced Polymer (CFRP) composites, which are lighter but at least equally stable.
Carmakers like BMW and carbon fiber manufacturers have teamed up to replace
major car components with CFRP. These are just two examples of how new
materials are revolutionizing the manufacturing industries.

Boeing and CRFP Technology

Carbon-fiber-reinforced polymer or carbon-fiber-reinforced plastic (CFRP or CRP or often simply carbon fiber), is an extremely strong and light fiber-reinforced polymer which contains carbon fibers. The polymer is most often epoxy, but other polymers, such as polyester, vinyl ester or nylon, are sometimes used. The composite may contain other fibers, such as Kevlar, aluminium, or glass fibers, as well as carbon fiber. The strongest and most expensive of these additives, carbon nanotubes, are contained in some primarily polymer baseball bats, car parts and even golf clubswhere economically viable.

Usage of CRFP in Super Cars

The Relation of Carbon fiber-reinforced polymer (CFRP) with A Supercar

The Lexus LFA is a two-seat supercar from Lexus. It is the second model in the F marque line of performance vehicles from Lexus, following the IS F. As well as its low weight and high strength, carbon fibre reinforced plastic (cFrP) also gave the LFA’s designers a far higher degree of design freedom, allowing them to create shapes, curves and edges that would have been impossible with metal.

The production Lexus LFA features a new V10 engine and a carbon fiber-reinforced polymer (CFRP) body. CFRP materials account for 65 percent of the LFA's body composition by mass.

Technology of Carbon fiber-reinforced polymer (CFRP)

DIALEAD composite is a carbon fiber composite material compressed by resin. The formal name is carbon fiber reinforced plastics or CFRP. Taking advantage of excellent properties not available from conventional metals and ceramics, the product is widely used in various applications.

Another Applications of CFRP

The coefficient of
thermal expansion can be controlled by optimizing carbon fiber mixing, and can
be made to zero, depending on design.In addition to low thermal expansion,
lightweight, and high stiffness, heat sink and other thermal controls can be
realized, utilizing the product's property of thermal conductivity only in the
orientation of the fiber.
